Simulationof Direct Current (D.C) Electrical Motor Speed Control
Journal Title: American journal of Engineering Research - Year 2018, Vol 7, Issue 7
Abstract
Mathematical equations describing the voltage and corresponding rotational angular speed of the DC motor were applied and simulated using MATLAB.The desired Direct Current (DC) motor speed control is realized by the proper design and implementation of the Proportional (P) controller. Results from the analysis of DC motor speed control showed that when 1 volt was applied to the system, the motor could only achieve a maximum speed of 0.1 rad/sec, which was ten times smaller than the desired speed. For a unit-step input, the DC motor angular speed had dynamic response with settling time, steady-state error and percentage overshoot of 2.070 sec, 0.853 and 0.000% respectively. The implementation of the proportional gain πΎπ from proportional controller reduced the steady-state error. However, increasing πΎπ often resulted in increased overshoot with too large steady-state error, therefore, it appeared that not all of the design requirements could be met with a simple proportional controller.
